, p. 1281 - 1288 (2021/09/30)
Abstract: A series of new asymmetric ureas, urethanes, and other derivatives of the framework structure have been synthesized by the reactions of adamantan-1-yl isocyanate generated in situ by the thermolysis of carbamothioates with nitrogen-containing nucleophiles and alcohols.
Aluminum triflate as a powerful catalyst for direct amination of alcohols, including electron-withdrawing group-substituted benzhydrols

Direct aminations of allylic alcohols, benzylic alcohols, and benzhydrols with electron-withdrawing (F, Br, I, NO2, or CN) substituents were efficiently catalyzed by aluminum triflate [Al(OTf)3] to afford the corresponding biarylamines in high yield, and the dibromo-substituted product was further transformed into letrozole.

Amberlyst-15 catalyzed Cbz protection of amines under solvent-free conditions
Bora, Pranja P.,Vanlaldinpuia, Khiangte,Rokhum, Lalthazuala,Bez, Ghanashyam
experimental part, p. 2674 - 2683 (2011/08/22)
Amberlyst-15 can effectively catalyze Cbz protection of aliphatic and aromatic amines within 10-15 min under solvent-free conditions. The catalyst can be used repeatedly without loss of activity, and the reaction requires no workup and gives excellent yields. Taylor & Francis Group, LLC.
An excellent method for Cbz-protection of amines
Vanlaldinpuia, Khiangte,Sema, H. Atoholi,Rokhum, Lalthazuala,Bez, Ghanashyam
experimental part, p. 228 - 229 (2010/08/20)
Cbz-protection of aliphatic and aromatic amines can be accomplished with benzylchloroformate using a catalytic amount of dodecatungstophosphoric acid hydrate (0.05 equiv). The reaction is simple, fast, does not require aqueous work-up and gives excellent yields.
